Hello, I’m trying to get a player card working, and the validator won’t render my card. I’ve spent awhile trying to figure out why (this is a revision of an existing, perfectly functional player card) and I can’t figure out what could possibly be wrong.

I updated the meta tags to (I think) point at the domain properly. When I test this in the validator, I get “Unable to render Card preview”. This leaves me to wonder if a) I’m missing something really basic, or b) there’s something wrong with the validator. Help???
